MEMQRANDA 'naviera Applicationled March 11, 192.2. s Serial No.`543,100.

The present invention relates broadly to memoranda and reference devices forv general information orv notation, and more particularly to devices of this nature of compact construction whereby they may be conveniently carried inthe pocket or held in the hand and adapted for use by public etc., or by commuters, advertising promoters and others requiring condensed information, schedules of eventsor convenient notation or reminder devices; f n

ln my United States Patent No. 1,412,043 of Aprilv 11, 1922, there are illustrated several forms of devices of this general nature, certain of which are duplicated and claimed herein, together with modifications and improvements,whereby the present application constitutes a division lin part and continuaf tion in part of application Serial Number 496,127, which eventuated as said patent;`

This `invention contemplates improvements in devices of this general nature as heretofore provided, and embodies a plu-` rality ofradvantageous features, facilitating operation and use of the indlcia carrying or notation receiving member or members, together with novel means for holding said In the accompanying drawings I have illustrated several forms of my invention for the purpose of giving a clear understanding thereof, but it will be applarent that various changes may be made in t out departing from the spirit of my invention or scope of mybroader claims.

Figure 13 is a sectional view'on the line XIII- XIII of Figure ll. l

I am aware that it has heretofore been proposed to construct various forms of pocket indicatorsor calculators comprising a rotatable indiciaV carrying or receiving member, but so far as l am aware such devices have never been provided with a readily removable and renewable member of this character, or with means cooperation therewith tending Vto hold the member in proper position or for indicating in the manner of the present invention the proper registry of the respective parts. 1 i

By the usey of the present invention a speaker may deviateat will from a certain course without fear of omitting some important feature, and theV strain induced where subject titles must be memorized, is

eliminated.; In like manner, it is adapted for use by any one requiring condensed, tabkinds on widely different subjects, or by anyy one desiring to make miscellaneous notations for future reference or consideration.

Referring more particularly Yto the drawings, there is illustrated in Figures 1 11nd,.

2 one form of my invention comprising ay casing constituted by relatively movable members 2 and'3, which in the form shown are provided with a hinged connection 4. TheV member 3 may be provided kwith a spring operated catch 5. adapted to2 engage asuitablyshaped detent 6 in themember 2, whereby the parts may be held in assembled relation. Each of the said members v2 and 3 y have inwardly turned ilangesvor ed es, asl shown, around the greater portiono their y perimeter, the flanged edges cooperating to hold the members in properv spaced relation, and also serving to partially enclose the casing'` 'Projecting inwardly from the.A member 3 are hubs 7, adapted to vhave positioned thereover indicia carryin orreceiving members such` as disks 8. hese -disks may be each providedwith one ormore division lines 9 extending in any desired difili the disks as Well as access thereto.

rection thereof, for dividing the disks into a plurality oi sectors or divisions. 1 preterably form the lines 9 under considerable pressure, whereby they lie below the 'main surface of the disks Vand arepreyented troni becoming rubbed or smeared in use. It' desii-ed, indelible ink may be advantageously used for this purpose.

Each member `of the `casing may be -provided ivith one or more reading openings 1() Jformed therein in any desired manner and adapted to permit operation and inspection One ofthe casing `meinl'iersmay be provided with an eye`11 ot any desiredconstruction, Where Lbythe 'entire 'device maybe carried on a 'chain or the like, itdesired.

`Vith 'the forni otmy invention described, the 'disks 8 "carried on the respective hubs Within the casing, 'may be so designed to 1Jfriotion'gail'ly bear one against the other,

ivhereby Ya 'too free 'rotation ot the disks is prevented and they are held frictionally in 'the desired lposition.

In Figures 3 'to 5 of the drawings there is illustrated a form "of my vinvention correspending generally totliat shown in Figures 1 and 2 and for Vthe sake of breviltyll have indicated parts corresponding to the parts already described With the same reference ein actershaving an a aiiiined thereto. In this 'forno of the invention either one or both. oii'the casing members may be provided -With pockets 12 formed therein `in anl sired'inanner and at any 4desired pos` 13 which Amay receive 'or carry any desired information.' The disks 13 may be conven- `iently rotated Aby providing Acutaway `portions 14 in the member n'3l,-"as illustrated,

l and the `pockets 12 may be vprovided ivith reading Yopenings 15, permitting the Vdesired access to Athe d1`sks` In some instances it may be desirable to provide lugs 16 pro- 4'eating inwairdlv a slight distance from the `edges oit the .pockets necessitating springing the disks intoposition whereby they aire prevented from becoming Vdislodged. while the device is in juse.

Figure (6 yof the drawings illust aies a compound casing 17 having pockets Jformed *thereim'accessto'which is provided through peripherally entending slots 18. These pockets are adapted to receive disks 19 `havling a plurality tjnjotches or "depressions 2() "formed *therein and adapted to be engi-iged by "a detent "21""Whereby` the "disks are held "fricti'onally 'in'position "and desired regisi tration may be audibly indicated.

In'Figure 7 thecasing'22 is illustratedas having a cutaway portion 23 adapted to permit operation of the 'disk 24. rlhis disk may be provided With notches or 'depressions 20l corresponding With depressions 2O before described, and adapted to be triction'ally engaged by a detent 21a.

in Figure 8 I have shown a modified form oi disk 25 as having an opening 26 extending theretl-rrough. This construction is desirable Where a plurality of disks are iised `in superimposed Y-relation as *the openings permit access vto the sides 'of intermediate disks 'or to the inside surfaces fof adjacent disks.
